Upgrading Geophysics Computer Facilities at USC

该合同提供了购买计算硬件和软件以升级南加州大学地质科学系地球物理计算设施所需资金的51%。该大学承诺提供剩余49%的资金。改进后的计算设施将用于计算密集型研究项目，包括：调查震源性质、近场效应和对大地震的场地响应；尾波Q与地震过程有关的时空变化；利用多通道地震反射剖面描绘美国西南部的地壳结构和演化；研究断裂带的摩擦和断裂不稳定性；以及地下核爆炸震源机制的损伤力学方法。

This award provides 51% of the funding required for the acquisition of computing hardware and software to upgrade the geophysical computing facility in the Department of Geological Sciences at the University of Southern California. The University is committed to providing the remaining 49% of the funding. The improved computing facility will be used for computationally-intensive research projects that include: investigation of earthquake source properties, near-field effects and site responses for large earthquakes; spatial and temporal variations of coda-Q in relation to earthquake processes; depiction of the crustal structure and evolution of the southwestern U.S. using multichannel seismic reflection profiles; study of friction and fracture instabilities in fault zones; and a damage mechanics approach to the source mechanism of underground nuclear explosions.
